/*
 * Gotify REST-API.
 * This is the documentation of the Gotify REST-API.  # Authentication In Gotify there are two token types: __clientToken__: a client is something that receives message and manages stuff like creating new tokens or delete messages. (f.ex this token should be used for an android app) __appToken__: an application is something that sends messages (f.ex. this token should be used for a shell script)  The token can be transmitted in a header named `X-Gotify-Key`, in a query parameter named `token` or through a header named `Authorization` with the value prefixed with `Bearer` (Ex. `Bearer randomtoken`). There is also the possibility to authenticate through basic auth, this should only be used for creating a clientToken.  \\---  Found a bug or have some questions?
